palette registers not writeable #16

Palette needs to be reimplemented as dual-port block ram so that fastio side can write to it. Also consider making palette 1024 entries, with some bits to select the palette to use. Also consider allowing sprites to pull from a different such "palette bank" to the character/bitmap display.

Fixed. Palette is now writeable. Also $D090 now works for selecting active palette bank and which palette bank is mapped in $D100 - $D3FF.
